Academic Chemistry NCERT Class 10

Atomic number = 16

Electronic configuration = 2, 8, 6

i. Number of valence electrons in its atom = 6

ii. Valency = 2 (8-6= 2).

iii. Group number =16

iv. It is a non-metal (as it has more than 4 electrons in its valence shell).

v. It forms an Acidic oxide as it is a nonmetal
